From the material that we discussed in the lecture about the block cipher, answer the following questions: 110 bits Plaintext Key (K) Encryption algorithm Ciphertext 110 bits (a) Suppose that a block cipher that is shown in the figure above, uses a pure random permuted table with 110-block. What is the total number of 1-bit register that is required to build this pure random premuted table. (b) Now suppose that this cipher is implemented as a function as shown in the figure below. What will be the total number of 1-bit register that is required to build this function cipher?
